Will be on Ocean Princess 29 Oct-12 Nov, but will be doing QE2 Carib 22-27 Oct first - lots of time for comparing and hope to do a decent review of both - I realize it'll be perhaps unfair to compare the 2.
I've done Dolphin SeaBreeze (2x) & Ocean Breeze, Regent Sea, Carnival Tropicale (2x), NCL Wind, Crystal Harmony (fave).
